Kobe, Japan–Acknowledging the hardship being faced by people back home following the demonetisation of Rs 500 and Rs 1,000 notes, Prime Minister Narendra Modi on Saturday said more steps could be taken to curb black money as warranted.

Addressing the Indian diaspora here, Modi said he had already opened several windows for people to come clean on their ill-gotten wealth. After that, he said, he had to think of other ways and demonetisation was one such step — a matter that had to be kept secret.

He said that after the window offered in September for people to declare their unaccounted wealth, Rs 125 lakh crore was received by banks. “If after this you think that the situation remains like before then it’s not my fault,” he said, adding that after the demonetization scheme, “there is no guarantee that more won’t follow”.
